10Gtek [2 Pack] Gigabit Ethernet Media Converter with a 1Gb SFP SX LC Multimode Module, 10/100/1000M RJ45 to 1000Base-SX, up to 550m, with a British Power Supply

Good quality and perfect for the job at hand

I recently upgraded from a copper to an optical backbone in my home, and used these transceivers either end to convert back to the legacy copper trunks. They are easy to install, "plug & play", working well so far. Value for money was reasonable.

Used these for a client who had ongoing persistent issues with getting decent internet connectivity in their garden room. They had tried dozens of options including WiFi extenders, power line converters and even a cat6 cable, but the distance was just that little bit too far. Used these with an optical cable and it has transformed the connection. Absolutely perfect. Will definitely use these in the future, as they just do exactly as designed with no drama.

1st pair purchased didn’t work, 2nd pair worked flawlessly, now in use to link buildings together over 400m apart.

One of those items you never knew would be so useful! Once plugged in, it just works! No configuration required. I have used it to extend ethernet about 300m meters without issue. Another useful thing, is I use these to extend managed networks which have security embedded on - i.e. only allowing one MAC address per port. These converters don't add any MAC addresses or additional information to the network traffic, hence can't be seen by the managed network.

I needed to connect a 100Mbit/FE BTOR FTTC modem to a router which would use PPPoE. The router only had 1GbE ports that were fixed speed negotiation so I needed a media converter to sit between the two devices that supported store-and-forward. I bought the version of this converter without an SFP module so I could put a 1GbE copper RJ45 SFP module in to connect back to the router, and use the auto-negotiation RJ45 port on the converter to the modem. It has been working flawlessly for 2 weeks now.

Great product, very easy to use

Despite listing specifying a UK power supply, was sent a US one. Functionality is ok, but disappointed in having to source another power supply EDIT: 10Gtech reached out and apologised for the mix-up and have sent a replacement power supply, excellent customer service and product

I had 125' LC to LC fiber laying around that I wanted to put between my cable modem and router. I purchased two of the 1.25Gb/s SFP Module to 10/100/1000Base-Tx, with a 1.25G 850nm 550M SFP media converters and plugged one in on each side and connected the fiber. I removed my 50' ethernet cable and plugged a 3' one directly between the cable modem and media converter. I did the exact same thing on the other side and everything came up immediately. Lost a total of 5 pings, and my routers IP address did not change. (the cable modem has no idea these are in-between). As far as a performance test goes, my average ping time to my cable modems default gateway may have went up by about .25ms average over 100 packets, but that could just be the neighborhood I am in. I am more than pleased with this simple solution to protecting my network from a lighning strike on the cable lines around my house. Also - I purchased a 3rd one as well as a 10Gtek for Cisco GLC-SX-MMD/GLC-SX-MM/SFP-GE-S, Gigabit SFP SX Transceiver to plug directly into my network switch. I just trenched a 6-10" trench to my shed and will be placing the media converter in there along with an access point which is about 80' from the house plus about 35' of internal cable. I have already tested the 3rd one along with the SFP module in my switch and they connected right up. As long as I dont have any issues running the fiber, this is another great use for these to protect my internal network from both near lighning strikes as well as static differential between the buildings. While I cant take advantage of POE (Power Over Ethernet) to power the aceess point, I think the isolation definatly outweighs the benefits of POE. So far I have less than 30 minutes with these in use (2018-10-21). If you dont see an update from me, they are still working.

目的を達成できた。

Excellent Transceivers for Fiber. I like these a lot. They seem to be reliable and no software/firmware setups required. True Plug and Play! Seems to work quite fast with no issues

fast shipment. works well.

コンパクトで、LCコネクタを接続するコネクタが金属でできており、光ファイバケーブルの保護的な役割をもっているので、ケーブルの取り扱いが非常にしやすいです。 大手メーカーの1/4程の価格で、コストパフォーマンスも素晴らしいです。
